“We shot a scene in Wayne Enterprises together, and it was just the two of us, just these two women breaking the ice with each other,” Melissa told EW. “It’s rare that I get scenes like that. I have scenes like that with Grant [Gustin] and Stephen [Amell] all the time, but I was very excited to do that with another strong female. I’ve not really gotten to have scenes like this with other female characters [like] Sara Lance [Caity Lotz] or Black Canary [Juliana Harkavy]. In the way that Barry and Kara are so light and such good friends, I think Kate and Kara have a lot more in common and can really understand each other.”

“It was nice because when Kara met Kate, it was in Kate’s space, and it was fun because there’s this power dynamic,” Ruby, who makes her debut as Batwoman in the crossover, added. “You got someone like Kara, who is just so sweet and nice, and I think [with] Kate, who is not one to trust people and doesn’t really have a lot of time for what’s happening right now, you see it’s impossible not to be charmed by Kara. You see the warmth in what I think would be a budding friendship. But it’s also really fun making Melissa/Kara uncomfortable.”

The actress, and future Flash director, opened up in a new interview with ET about Ruby joining the fandom as Batwoman in the upcoming crossover, Elseworlds.

“It’s fantastic [to have her here]. I think it’s an excellent addition to the universe,” she shared. “Obviously we have Supergirl, and that’s a really great step for telling female stories. I think Batwoman is another step in that direction, but it’s also gonna be different and unique.”

“She’s gonna have her own journey and her own world. I’m pretty excited about it,” Danielle added.

Danielle also talked about the feel of the crossover itself, saying that “it’s great — I feel like they did a really fantastic job writing the crossovers this year.”

“You know, rather than being about, ‘How many superheroes can we get in one room?’ they’ve told a really great story [this year]. Obviously, we’re introducing some exciting new characters, and I think fans are gonna love it.”

The event will be hosted by Jordan Fisher, Ruby and Dakota, and in the half-hour special will feature star-studded musical performances and special appearances by Disney Channel stars Booboo Stewart, Kylee Russell, Sadie and Sean.

Meg will actually be performing her rendition of “Mele Kalikimaka” for the event!
